The VCM-DAS-1 module provides a combination of analog I/O, digital I/O, and non-volatile storage, which makes it ideal for data acquisition and control applications. All of its functions are provided on a single 3.8 x 3.6" PC/104 module. The analog input section features 16 single-ended input channels with 16-bit resolution, fast 10 µS conversion, and a ±5V or ±10V input range (153µV or 305µV resolution). Throughput of up to 100 kHz may be realized with conversions on one channel and up to 67 kHz when scanning between channels. A variety of automatic channel scanning and triggering modes are available, including DMA support. The analog output section includes two 12-bit analog output channels. Each may be jumpered independently for 0-5V or 0-10V output. Both sections feature simplified calibration using programmable digital pots. In addition, the on-board EEPROM which is used to store the calibration values has free space available for user data. The digital pots power up and reset to mid-scale, and can be set to any calibration value during system initialization. The digital I/O section provides 16 digital I/O lines which feature high current TTL drivers. The two 8-bit ports are byte configurable as inputs only or outputs with readback. The digital interface is plug compatible with Opto 22 type modular I/O racks.
